The presentinvention relates to seam-pressing crease set into engagement with the worksupport machines, and more particularly to that type by a fin, projecting forwardly from theseamthereof which is used in the manufacture of pressen'which, while the'seam-crease is unsupmens shoes topress the back seam joining the ported and the opposite faces of the seam ridge quarters.

The illustrated embodiment of the present in- 55 T e Sea -r may be preformed d the .S'eamvention operates upon a work piece comprising 0 7 into the block 31.

two quarters 11 and 12 (Fig. 8) which are sewed together by a curved line of stitches 13 concentric to the adjacent edges. If the quarters are leather, the faces engaged in Fig. 8 are grain, the flesh faces being exposed. The quarters are opened up (Fig. 4) to present a seam-ridge 14 on one face of the work and a seamcrease- 15 on the otherfac'e of the work. i

In the "machine the workis'supportedupon a roll 16 for the operation of a seam-presser or hammer 17 and a heated seam-settingor rubbing tool 18 which may have the same relative modes of operation as the correspondingparts' disclosed either in the patent to Staples, 1,234,950, July 31,

1917, or the application filediconcurrently-herea with by Walter P. Osgood. "In either event,'the hammer 17 operates in a four-motion cycle moving substantially vertically to press the seamridge, horizontally to the left (Fig.1) to feed the work, vertically to leave the work, and horizontally back to the right-(Fig. 1) tocomplete the cycle.

'In order topresent the seam-ridge properly to the work support 16, .the machine is provided with aI-gufde l9'engagedin the seam-crease, a guide embracing the opposite faces of the seamr e, and a-"gage 2 1 engaging the free end face of'the seam-ridge. The samrcreaseguidew' is secured by a screw .t'o apostcarriedby the frame of the machine. The free end o f'the. guide 19 terminates close to worksupport 16 Near its free end the guide isprovided a horizontal portion 23 having a he elsdedse' Figfer n es m tin t m- .gg i e v n v c The seam ridgeoguide '20 comprises two members 24'and-I25 arranged to embrace the opposite sides of the seam-ridge. As shown particularly in Fig. 2 the members 24 and 25 flare inwardly the direction the work is fedtherethrough. members 24'and 25 are formed on vertical arms of bell-crank levers 2'6 and 2'7 .(Fig.'.4-) which arepivoted, respectively, 1 on horizontal pins "28 and' 29 which bridge a recess 30 (Fig. 3)-formed i n a block 31. The-bell-crank lever'26 is providedqvith a recess 82'(Fig.'4-) which receives a '33 on'the bell-crank lever 27 order. that the. spreading movement of the members-24 and 12 5 14nder-the influence-of the. seam ridge may be mutual. The bell-cranklevers 26 and 2'? are en d, re e vel b sh nes arena 35. h us d in e blo kmi e t a h m m er and "25 may normally? have a tendency to assume a closed. position. The-movementof the members '24 and 25 towards'each other-is limited ads justably by a cam 36 formedas an eccentric on a'stud' 37"ha'vifig aslotted 'h'ea'd engaged with one wall cf-the recess 30jar'id -a'tl1raded shank en eed' fl h i ii g Wa et" th ec 30.

The block 31 is'proyidedwitha horizontal way ea h c' lis en e b te n' 40 carr ed laye lower end of a rod 41"mounted to slide vertically in bearings 42 in a bracket 43 secured to-the f1? e'of the machine The-tench 40 'is provided wi'tlf ahorizontally extending slot 144 which embraces 'the' shank'of a headed screw 45 threaded With this; construction the position of the blo'ck'31 with relation to the tenon 40 may be varied to provide for-the lateral adjustin'ent'hf the seam-ridge guide'20. I V

In order to permit the searn-ridge guide 20 to yleldvelrtifcally the rod 41' 'is'p'rjovidd with a 001- lar 46. Coiled about the rod 41 is a spring 47 which is interposed between the upper bearing 42 and the collar 46. The rod 41 near its upper end is provided with a, lateral block 48 similar in construction and mode of operation to the corresponding block disclosed in the patent to Staples hereinbefore referred to.

The gage 21 comprises a horizontal part 49 (Fig. 7), provided with a groove 50 on its bottom face to receive the free end face of the seam-ridge, and a vertical part, provided with a vertically extending slot 51 which embraces the-shank ofa screw 52 in a manner permitting the vertical adjustment of the gage 21 and its retention in the desired adjusted position. The horizontal part 49 .of the gage 21 extends parallel and close to the supporting face 23 of the seamicreaseguide 19. The gage 21 is prevented from moving laterally relative to the seam-crease guide *by'the walls of a slot 53, formed in the block 31, which engage the opposite sides of the rectangular head 54 on the vertical part of the gage 21.

After the quarters are opened up the seamridge is introduced between the flaring front ends of the members 24 and 25 of the guide 20.

Thesemembers converge towardseach other in the direction the work is fed so that as the seamridge-moves rearwardly the members 24 and 25 embrace the opposite sides thereof and confine the sides ofthe seam-ridge to a predetermined path. The members, under the influence of 'the 'seaIn-ridge, move. laterally .to accommodate 1 themselves to the. thickness of the seam-ridge. "These lateral movements of the members 24 and 25 are mutual so that the median lines of the seamridges inserte'd ,SUGcessiVely into the ma.- chine are all in the same vertical. plane not.- withstanding variations in their thicknesses. At the same time the sides of the seam-ridge are en.- gaged by the members 24 and '25, the seamcrease and the end face of the seamsridge are engaged'by'the guide 19 and the groove 50 in the gage :21, respectively. The seam-ridge" is pushed through the space bounded by the guides 19 and 20and the gage 21 untilthe' leading end of the seam ridge projects, unsupported from below, beyondthe'free end of the seam-crease guide. At this point, a fin 56 projecting forwardly from the'hammer '17 into the space between the members 24 and 25 which confine laterally the leading end-of the seam-ridge, steps upon the unsupported'seami-ridg'e. The fin 56 has a width narrower than the free end edge face of the upstanding seam-ridge so that when it steps on the unsupported seam-ridge it forms, a groove 57 (Fig. 9) in the material forming the free end edge face and displaces the material directly under the groove'to set the seam-crease firmly into engagement with the peripheral surface of the workjsupport.

' The-'workengaging face of the. fin 56 is roughened so that when the hammer 17 is moved to the left (Fig. 1) the fin 56 feeds the depressed seam ridgeto the left. After the hammer, 17 reaches its extreme position 0t movement to the leftin" contact with the Work, the hammer 17, together with the fin 56, is'elevated from the work ,-r eturns out of contact with the work to its extreme position to the right (Fig. 1), and g confined but unsupported from below seamvridge, andthe-hammer 17 strikes the. walls of the groove 5?;previouslyj formed by the fin 5.6,

but now unconfined. laterally by the seameridge guide; and rolls them outwardly into engagement 'with the adjacent faces of the work pieces,

(Fig. 10). V

of the groove 5'7 by the fin 56,

by the hammer, and the four-motion feeding movements thereof continue until the seam-ridge passes beyond their influence. In the meantime, the portion of the seam-ridge previously operated upon .by the hammer 17 is fed'ben'eath the heated :tool l8which sets the'seam in the position .to

which it'has been brought by the hammer 137.

Nothing herein explained is to be interpreted .as limiting the various features of the present invention in the scope of its application to use in connection with the particular machine 'or the particular mode of operation or both selected for purposes of illustration and explanation. While the-particulars of construction herein set forth are well suited to one mechanical form of the invention and to the use to which it is put, it is not limited to this use, nor to these details of construction, nor to the conjoint use of all its features, nor is it to be understood that these particulars are essential since they may be modified within the skill of the artisan without departing from the true scope of the actual in vention, characterizing features of which are set forth in the following claims by the intentional use of generic terms and expressions inclusive of various modifications.
